Under the guise of Popol Vuh, the Munich-based Florian Fricke created one of the most original bodies of work during the 1970s. His first two records were krautrock of the most kosmische type. Released in 1970, Affenstunde ("Monkey Hour") saw Fricke's hand on the Moog synthesizer; he was one of the first in Germany to own one. By 1972, he had switched to organ for the following In Den Gärten Pharaos (now recording for the Pilz/Ohr label), but had yet to find the quintessential Popol Vuh sound.
The debut album from Heldon introduces French electronic rock pioneer Richard Pinhas and the larger Parisian counter-culture he piloted. Though he left his teaching post at the Sorbonne, Pinhas never left his philosophy behind. His work would always remain left of center, as the title Electronique Guerilla attests; and the spirit of the May 1968 student revolt remained the key to both his musical invention and dedication to his uncompromising spirit—Heldon sound like little before it.
